View full lesson: https://ed.ted.com/lessons/how-do-solar-panels-work-richard-komp The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. Lesson by Richard Komp, animation by Globizco.

12 of those panels to power my cell phone ? wtf kinda effeincy is that ! these scientists need to get their head out their ass and do better then that bs ! 12 of those tiny panels i want to power my laptop , watch tv , and cook dinner on an induction plate ! all on demand ! no wonder the world isn't going forward ! the ratio sucks balls ! fix that stupid low ass efficiency rates ! GTFO outta here with that bs

1:12 If electrons can cross over to the other side of the junction wouldn't they do the exact opposite of that, namely balance the system, settling in the holes and thus neutralizing the system?

Solar Power is an absolute fraud; we need to go back to coal mining and drill more oil refineries for energy.

didn't Germany successfully turn their power grid to solar

by playing to the emotions of the unsuspecting public who think the sun is free energy.
Thereby extracting billions from the pockets of the unsuspecting public while making them all feel warm and fuzzy thinking they are saving the planet when behind every solar panel and its lifetime solar energy is the pile of non renewable energy to make and transport them, thus filling the solar industries pockets with our money and producing nothing but toxic garbage and using up non renewables. -
then sun is going to be god again. once in agricultural ages. now in electrical sun energy culture

"nothing to get warn out or used up" not true, the other chemicals used for photovoltaic cells do wear out and collecting these resources is environmentally costly. Sorry, but solar panels aren't the answer as of yet.

INCORRECT.
THAT IS NOT HOW A SOLAR CELL PANEL WORKS
REPEATING WHAT YOUR PROFESSOR IN COLLEGE SAID WHO ALSO WAS REPEATING IS
SIMPLY ERROR.

46% is better than coal and nuclear

Depnds on the type of solar cell
-
oh sure, downplay the busines and political side

my friend has a business opportunity offering Solar to people through a bunch of Solar Providers. Its really cool and you can make some good commissions doing it. check it out at powur.com/james.peterson/learn or get a FREE Solar Proposal from him at powur.com/james.peterson/getsolar

Anyone has sources about why politics and economics prevent usage of solar energy?
-
is the "electric field in the pn junction " an extrenal electric field?
-
Really good stuff..

I have a minor confusion: when the electrons get "knocked out" by the photons and holes are created, shouldn't the hole get attracted to the n-type- excess electrons- and the electron to the p-type - excess holes?
